Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 2-5, the embodiment of the present invention provides a suspension rod system part rubber bushing, which comprises an inner sleeve 2 sleeved on a bolt 1, a rubber layer 3 sleeved on the outer side of the inner sleeve 2, and an outer sleeve 4 sleeved on the outer side of the rubber layer 3, wherein two ends of the inner sleeve 2 along the axis are abutted on a bracket 11 for mounting the bolt 1. The support 11 is arranged on two sides, the bolt 1 penetrates through the middle of the support 11, the end part of the bolt is connected with the nut, the nut is screwed on the support 11 to clamp the middle inner sleeve 2, and the inner sleeve 2 extends out of the rubber layer 3 and the outer sleeve 4 towards two ends.
The bolt further comprises a reinforcing sleeve which is arranged between the inner sleeve 2 and the support 11 and can increase the contact area with the support 11, and the reinforcing sleeve is installed on the bolt 1.
